Signal Vault - how does the RFID blocking cards work?


New Member

I watched Shark Tank a couple of weeks ago and there was a guy that had developed a card that blocked RFID scanners to read information from your credit cards ( and I couldn't figure out how the cards were working. Can anyone tell me how the technology works - they mention efield technology and white noise, but me being suspicious calls BS on the product. I don't have enough knowledge of RFID and how it works. Can anyone here tell me if it works, and if it does, how does it actually work?
